Audio Outputs
Using the Separate Outputs
18-3
Hardware Audio Switching
ItÕs important that you understand the effect on the MIX outputs when you use the separate
outputs. When you connect a standard audio cable to any of the separate outputs,
every sound
(or part of a sound) thatÕs assigned to the output you connect will be removed from the MIX
outputs. For example, imagine that you plug a cable into the left output of Group A. The left
side of every program layer assigned to Output Group A will disappear from the left side of the
MIX outputs, and will appear only at the left Group A output. If a layer is panned all the way
left, it will disappear from the MIX outputs entirely. If itÕs centered, the left side will disappear,
but the right side will remain at the right MIX output. A layer thatÕs panned hard right will not
be affected in this case. If you use all eight separate outputs, the MIX outputs will not carry any
signal.
The pan settings you make on each programÕs OUTPUT page apply to the separate outputs just
as they do for the MIX outputs. Keep in mind, however, that the signal at the separate outputs
will always be dry; only the MIX outputs make use of the global effects processor.
Once you have the output groups assigned on the OUTPUT page, you can go to Master mode
to specify how the signal will appear at the MIX outputs. On the Master mode page are three
parameters that affect the routing of all signals that are sent to the MIX outputs. The settings for
these parameters will affect each layer in every program.
The parameters Out A->Mix and Out B->Mix determine the panning of the A and B GroupÕs
audio signal at the mixed outs. If theyÕre set to Stereo, then whatever panning is applied to each
program (as set on the OUTPUT page in the Program Editor) will show up at the MIX outputs.
Output groups C and D are permanently set to Stereo.
If either of these parameters is set to Mono, then programs routed to the corresponding audio
output group will send all of their sound at equal levels to both outputs, regardless of any
panning that might be applied to them on the OUTPUT page. This is a quick and convenient
way to convert the MIX outputs into two mono outputs.
The parameter Out A->FX is intended for special cases when you want an additional separate
output that doesnÕt go through the K2vxÕs effects processor. A value of L Only bypasses the
effects processor for all sounds assigned to the right side of Output Group A. ThereÕs an
example in Chapter 11 that describes how to use this parameter.
Using Stereo Insert Cables
The preceding description of the separate outputs is only part of the picture. You can make the
separate outputs even more useful by using stereo insert cables. A stereo insert cable has a
single stereo plug on one end; the other end is split into two mono cables Þtted with mono
plugs. By plugging the stereo end of a stereo insert cable into one or more of the K2vxÕs
separate outputs, you can create all sorts of audio conÞgurations with outboard gear. The tip of
the stereo end carries the signal to the send side of the split end, and the ring of the stereo end
receives the signal from the return side.
Effects Return
Plug the stereo end of a stereo insert cable into one of the K2vxÕs separate outputs, then plug
the send (tip) side of the split end into an input on an outboard effects box. If you connect the
effects boxÕs output to the return (ring) side of the split end, youÕve created a loop that will send
the K2vxÕs output into the effects box, and return it wet to the K2vx. Since the loop returns the
signal to the same output jack on the K2vx, the K2vxÕs MIX outputs act as if there were no cable
at all plugged into the separate output, and the signal will appear at one or both of the MIX
outputs. If youÕre using one of the Group A outputs, you can apply the effect of both the
outboard box and the K2vxÕs global effects processor to the corresponding side of the K2vxÕs
MIX outputs. If you donÕt want to double the effects in this way, you can go to Effects mode, set
the FX mode parameter to Master, and set the Wet/Dry Mix parameter to 0%. You can also set
the Pan parameter of programs routed to Output Group A fully right, then go to Master mode
